DRIVING-BIT.

SPECIFICATION forming part of Letters Patent N 0. 762,213, dated June 7, 1904.

Application filed Jun: 26, 1902.

To all whom it may concern.-

Be it known that I, ROGER VVILLIAMs VAN ORNUM, acitizen of the United States, residing at Racine, Racine county, Wisconsin, have invented certain new and useful Improvements in Driving-Bits; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in driving-bits, and more particularly to an improved double mouth-bar bit.

An object of the invention is to provide an improved double mouth-bar bit wherein each mouth-bar is provided at one end with a reinring and at the opposite end with a head-stall ring and a separate overcheck-ring, whereby the overcheck-rings will be held against the u pper jaw of the animal, preventing the bit pulling into the mouth and applying pressure against the upper jaw simultaneously with the pressure of the head-stall rings against the lower jaw of the animal.

The invention consists in certain novel features in construction and in arrangements and combinations of parts, as more fully and particularly pointed out and described hereinafter.

Referring to the accompanying drawings, showing as an example one construction within the spirit and scope of my invention, Figure l is a perspective view showing the bit applied to the animals mouth as in use. Fig. 2 is a top plan view of the bit. Fig. 3 is an end view on a somewhat larger scale than in Fig. 2.

In the drawings, 1 is the head-stall, 2 represents the reins or lines, and 3 3 are the overdraw or check straps or connections.

The bit consists of the two similar mouthbars 4 4, each at one end provided with the single rein ring or loop 5 and at the opposite end provided with the ring, loop, or checkpiece 6 and the small ring 7. It will thus be noted that the bit in the example illustrated consists of two loosely-connected mouth-bars and six rings or loops loosely confined thereto.

Each bar 4 is shown slightly curved longi- 5 tudinally and at one end bent to form an eye Serial No. 113,344. (No model) 8, loosely receiving or through which the rein or line ring 5 loosely passes. The opposite end of each bar; is bent to form a somewhat elongated eye 9, loosely receiving or through which the two separate rings 6 and 7 loosely pass. This eye 9 is'usually so formed that the rings 6 and 7 are free to independently swing'laterally or to and from the sides of p the animals mouth, yet so that said rings cannot slip past each other.

The two mouth-bars at their central portions cross and loosely rest one on the other, and the rein -ring end of each bar passes through and is guided by the ring 6 of the other bar, so that the bars are disconnected except by the two rings 6.

When the bit is applied to the animal, the reins or lines 2 are applied or secured to the rein-rings 5 5, as usual, and the head-stalls 1 are secured to the upper portions of the guide and head-stall rings 6 6. The overcheckstraps are secured or applied to the overcheckrings 7 7.

The rings 6 6 extend rearwardly from their bar ends against the lower lips of the animal,

and the rein-ring ends of the mouth-bars bear against the rear or free portions of said rings 6 6.

The overcheck-rings 7 7 extend forwardly or upwardly along the upper lips of the animal, and when pressure 1% applied to the reins said rings 7 prevent the check pieces or rings 6 pulling into the mouth of the animal, and i said rings 7 press forcibly against the upper jawor lips of the animal and cause the overcheck-straps to press against the nose of the animal simultaneously with the inward pressure of the rings 6 6 against the lower jaw or lips of the animal.

By means of this bit great pressure can be exerted simultaneously against the upper and lower jaws of the animal without injury to the mouth and without the bit pulling into the mouth, giving the driver perfect control of the animal, and yet for ordinary purposes the bit is exceedingly easy on the animal and is also well adapted for gentle draft-animals.

Material advantages and the above-mentioned results are attained by employing the separate oVercheck-rings in the combination,

which permits the employment of the overcheck and causes the application of pressure to the upper jaw and prevents the bit pulling into the-mouth under strong pull on the lines or reins.

As at present advised I do not wish to limit myself to the forms or shapes of the rings and mouth-bars as shown, as these can be otherwise formed of different shapes within the spirit and scope of my invention.

Having thus fully described my invention, what I claim is- 1. The double mouth-bar bit consisting of the two independent swinging and longitudinally-movable mouth-bars, each at one end having the rein-ring and at the opposite end formed with the transversely-elongated eye,

and the two independently-swingable cheek rings confined in said eye one in advance of the other and extending forwardly and rearwardly therefrom, respectively, each monthbar extending loosely through the rearwardlyextending cheek-ring of the other bar,- whereby said two bars are confined loosely together by said rearwardly-extending cheek-rings, and the forwardly-extending cheek-rings project in advance of said bars, substantially as described.

2. A double mouth-bar bit comprising two loosely connected laterally and longitudinally movable mouth-bars, each bar having a rein-- in against. the upper jaw of the animal and the other cheek-ring adapted to extend rearwardly and independently swing in against the lower jaw of the animal, said bars confined loosely together by each passing freely through the rearwardly-extending cheek-ring of the other bar.

In testimony whereof I aflix my signature in presence of two witnesses.

ROGER WILLIAMS VAN ORNUM.
